Internet 75 speed

[wireless]

I have Internet 75 on a two year contract with unlimited data. In the past the down load and up load speeds were typically about 80Mbps. When I checked yesterday and today I got about 150Mpbs both up and down. I checked my plan and it still said Internet 75 with the same price but the speed was now given as 150Mbps. Not complaining but it seems odd that they increased the speed for no obvious reason. Anyone else seen this?
